1. Blood Administration Reference: http://rnbob.tripod.com/blood.htm 1. Only two units per filter. 2. Verify units. 3. Use within four hours after removal from blood bank. 4. Use 20 ga. or larger catheter. 5. Obtain Informed consent. 6. PRBC replaces RBCs only. 7. If more than 6-8 units of PRBC are given then give FFP with every other unit. 8. Give platelets one for every unit of PRBC after eight units. ESSENTIAL INFORMATION: 1. Clinical Pathology and Transfusion Medicine Guide 2.

Amphotericin and beginning transfusion of granulocytes or vice versa. It is advisable that all other blood products be separated from Amphotericin by two hours. Blood products must be hung within 30 minutes of leaving the Blood Bank refrigerator. The Blood Bank will usually only release one blood product at a time. However, with physician phone call multiple units may be issued during an emergency. Blood products MUST NEVER be placed in the refrigerator on the patient care unit. Check the appearance of unit for If appearance is suspicious, return it presence of clots, brown discoloration, to Blood Bank, as it may not be clumps or abnormal cloudiness, and appropriate for infusion. integrity of seals. Warming is not normally necessary and blood components should never be put in a bowl of warm water, on a radiator or in a microwave oven: this is dangerous, as it will damage the cells.

Tubing sets can be used for second unit of blood if used within four hours. As there is a possibility of delayed transfusion reactions, some hospitals require empty transfusion packs to be kept to enable testing if required. Packs should only be stored for the required time as they are a source of infection in themselves if left for extended periods.

Obtain 10 - 60 minute post transfusion CBC for post-count as indicated. b. Flush the blood administration set with 0.9% Sodium Chloride until the tubing is clear. c. Obtain and record vital signs. d. Disconnect and discard the empty blood product container in a contamination red bag. Adverse Reactions Pyrexia A temperature of more than 38 C might be due to: • n Pyrogens resulting from bacterial contamination. • n Reaction to white cells or platelets which can • also be accompanied by chills or rigors. • n Haemolytic blood reaction (see below). The appropriate action is to stop the transfusion and to seek medical advice.
6. Allergic reaction Allergic reactions can present as an urticarial rash or a mild pyrexia. This can also develop into oedema around the eyes or larynx and cause dyspnoea. Full anaphylaxis is uncommon. The appropriate action is to stop the transfusion and to seek medical advice. (Subsequent transfusions might require pre-medication with a prescription for an antihistamine and paracetamol.) Infection Although donated blood is screened for major viruses and bacteria (including HIV, hepatitis B, hepatitis C and syphilis), infections, although very rare, do occasionally occur. Much more common, however, is local phlebitis which occurs if a cannula remains in situ for too long: the most commonly isolated bacteria are staphylococci or corynebacteria. Platelets are stored at room temperature and so can act as an ideal medium for bacterial growth. The appropriate action is to check cannula insertion sites regularly for inflammation and infection, and to change the insertion site routinely every 72 hours. When using platelets, bags should be checked for discolouration, which may indicate the presence of bacteria. Haemolytic reaction A haemolytic reaction is caused by destruction of the donor red blood cells by antibodies in the recipient’s plasma. It can occur after only a few millilitres of blood are transfused, although a delayed reaction can occur up to two hours later. Haemolytic reactions can be fatal and as such, a suspected haemolytic reaction must always be responded to as a medical emergency. A haemolytic reaction is indicated by: • Breathlessness. • Collapse. • Tachycardia. • Hypertension followed by hypotension. • Chest or loin pain. • Subsequently, the patient might develop: • Disseminated intravascular coagulation (DIC). • Circulatory and respiratory failure. • Renal failure. The appropriate actions are: 1. stop the transfusion 2. disconnect the pack and giving set 3. maintain the intravenous line with normal saline 4. seek urgent medical advice. This is an emergency, life-threatening situation. Haemolytic reaction is most likely to be due to a patient receiving the wrong blood from one or more errors in the chain of events from taking a cross-match sample, the laboratory processes, the collection of blood for transfusion and administration into the recipient. All blood must be returned to the blood bank and an investigation must be carried out to ascertain the source(s) of the error. Circulatory overload Circulatory overload causes less of a problem now that concentrated red cells are used more frequently than whole blood. Problems can occur with older people, neonates or patients with megaloblastic anaemia. The action to take is to give diuretic therapy as prescribed, slow the rate of transfusion and observe closely for pulmonary and peripheral oedema. Iron overload Patients who receive multiple transfusions have an increased serum ferritin. At a level greater than 1,000mg per litre, the iron infiltrates organs such as the liver, heart and kidneys, which can lead to organ failure or even be fatal. In patients on multiple transfusion programmes, an iron chelater such as desferrioxamine can be prescribed to regulate the level of serum ferritin.
